  Next, the operation when the paper sheet P is switched to the A path by the suction guide type gate switching device of the present embodiment will be described. The following control is controlled by a control unit (control means, not shown) that controls the suction guide type gate switching device.

  When the paper sheet P is detected by the pre-gate sensor 8, the control unit controls the air valve 3B to release air from the air suction units 102 and 103 provided in the groove where the perforated conveyance belt 5A of the suction guide 1 is disposed. Suction is performed to adsorb the paper sheet P to the perforated conveying belt 5A. By this suction, the paper sheet P is transported in the A path direction, which is the traveling direction of the perforated transport belt 5A.

  The paper sheet P is further transported and supported by the pair of pinch rollers 14 supporting the perforated transport belt 5A and the A path transport belt 11, and taken into the A path. It is more preferable that when the suction guide 1 is sucking the paper sheet P, air is blown from the suction guide 2 to the paper sheet P and pressed against the perforated conveyance belt 5A. This direction is effective when conveying two continuous sheets of paper, the details of which will be described later.

When the leading edge of the paper sheet Pa is detected by the pre-gate sensor 8, the air valve 3B is operated to suck air from the air adsorption portions 102 and 103, and the paper sheet Pa is adsorbed to the perforated conveyance belt 5A. At the same time, air is blown out from the suction guide by the air valve 4B, thereby further pressing the paper sheet Pa against the perforated conveying belt 5A.

  In this state, the transport belts 5A, 5B, 11, and 12 are rotated so that the leading edge of the paper sheet Pa is transported toward the exit of the A path. After the leading edge of the paper sheet Pa is pinched by the A path exit pinch roller 14, the paper sheet Pa is conveyed in the direction of the A path exit without being suctioned by the suction guide 1.

  Further, since the mechanical parts do not operate on the conveyance path by switching the air valve 3B, the paper sheet Pa is not damaged even if the gate is switched (air valve switching) in this state.

  As the A path gate exit sensor 9 transitions to the dark state, the A path exit pinch roller 14 is regarded as holding the paper sheet Pa, the air valve 3B is switched, the suction guide 2 is in the suction state, and the suction guide 1 is in the blowing state.

  FIG. 4 is a schematic cross-sectional view of a suction roller type gate switching device according to Embodiment 2 of the present invention. FIG. 5 is a cross-sectional view of the suction roller 30 used in this embodiment. FIG. 5A is a front view of the suction roller 30. FIG. 5B is a diagram illustrating the air suction unit 301 of the suction roller 30. FIG. 5 (3) is an external view of the suction roller 30.

  In the second embodiment, the suction roller 30 (first suction roller) and the suction roller 31 (second suction roller) are used instead of the suction guides 1 and 2 of the first embodiment, and there is no hole. The configuration is almost the same as that of the first embodiment except that the separation conveyance belts 6A and 6B which are conveyance belts are used.

  That is, in the suction roller type gate switching device of the present embodiment, the separation conveying belt 6A extending from the one-way path (first path) through the suction roller 30 to the A path (second path), and the first A pair of separation conveyance belts 6B extending from the path through the suction roller 31 to the B path (third path) are provided in the conveyance path, and the paper sheet P is nipped and conveyed.

  In this state, the transport belts 6A, 6B, 11, and 12 are rotated, so that the leading edge of the paper sheet Pa is transported toward the exit of the A path. After the leading edge of the paper sheet Pa is pinched by the A path exit pinch roller 14, the paper sheet Pa is conveyed in the direction of the A path exit without being suctioned by the suction roller 30. Therefore, when the A path gate exit sensor 9 becomes dark and the A path exit pinch roller 14 detects that the paper sheet Pa is sandwiched, the air valve 3B is stopped and the air suction by the suction roller 30 is stopped.

  When the leading edge of the paper sheet Pb is detected by the pre-gate sensor 8, the air valve 4B is operated to suck air from the air suction portion 301 of the suction roller 31 and suck the paper sheet Pb.

  In this state, the transport belts 6A, 6B, 11, and 12 are rotated, so that the leading edge of the paper sheet Pb is transported in the B path exit direction. After the leading edge of the paper sheet Pb is pinched by the B path exit pinch roller 15, the paper sheet Pb is conveyed in the direction of the B path exit without being suctioned by the suction roller 31. Accordingly, when it is detected that the B path gate exit sensor 10 is in a dark state and the B path exit pinch roller 15 has pinched the paper sheet Pb, the air valve 4B is stopped and the air suction by the suction roller 31 is stopped.

  Again, in order to prevent the paper sheet Pa from being caught between the pinch roller 15 and the suction roller 31, or to prevent the paper sheet Pb from being caught between the pinch roller 14 and the suction roller 30. A fixed separation gate 7 is provided.

  By adopting such a configuration, the air control can be limited to only adsorption and stop, and the apparatus is simplified. This is suitable when the paper sheet is firm and does not require spraying.

The case where the blowing guides 40 and 41 of this embodiment are used in place of the suction guides 1 and 2 of the suction guide type gate switching device shown in FIG. 1 will be described as an example.

  When the leading edge of the paper sheet Pa is detected by the pre-gate sensor 8, the air valve 4B is operated to blow air from the air blowing portion 403 of the blowing guide 41 so that the paper sheet Pa is adsorbed to the blowing guide 40.

  In this state, the transport belts 6A, 6B, 11, and 12 are rotated, so that the leading edge of the paper sheet Pa is transported in the direction of the A path exit. After the leading edge of the paper sheet Pa is pinched by the A path exit pinch roller 14, the paper sheet Pa is conveyed in the direction of the A path without being sprayed by the spray guide 41.
